Abstract
Comparison and evaluation of root ability,growth of seedlings,height and ground diameter and the main genetic parameter estimation showed that between different clones existed genetic differences.The seedling height and ground diameter were much higher than the check,and the changing range of height and diameter was more.The heritability of tree height and ground diameter were,respectively,83.6% and 86.8%,and the rootability heritability was 90.2%,that showed genetic stability.Among the clones,No.0086,No.0006,No.0012 and No.0216 were thought outstanding ones.
